Be it known that I, RANsoM E. BEcKwrTtr.-

State of New Hampshire, have invented a new and useful or Improved Sash-Fastenin g; and do hereby declare the same -to be fully described in the following specification and repf resented 4in the accompanying drawing, of

Which- Figure 1 is a front elevation, Fig. 2 a top view, and Fig. 3 an end view, of it. Fig. 4 is 1 a. view of it with the ease-cap removed, the jsame showing the arrangement of the two :bolts and their actuatingspring. Fig. 5 denotes the arrangement of the fastening relatively to a window-frame, I, its two sashes K L, and the parting-tongue M of the next-couvtiguous grooves of such sashes.

' v'.lhe said sash fastening or lock is intend- 'j ed to be let into or sunk in a window-frame so that the-bolt-carrying projection may be within and make part of the parting -tongue Vbetween, the two next-contiguous sash-grooves, 'One of the bolts of the lock being shot forward andthe other retracted in order to effect the locking of the sashes. y

In the drawing, A denotes thelock-case, Vas made or provided with the bolt-carrying projection 1 3, and having a cover or cap-plate, O,all arranged as shown. The heads a b of thetwo bolts ,D E extend out of the case, and play through the proj eetion B, they, when boltv ed, extending, in opposite directions, out of it. f The shauks c d of the bolts are within the case, yand are provided with abutments c f, between which'and the shaiiks a helical spring, F, is arranged, as shown.

.n Speciicationvforming part of Letters Patent No. 133,9l6, dated December v17, 1872.

The heads of the knobs --may be sunk in a groove or grooves iiush with the windowframe so as not to 'interfere with the movements of a windowshade, or those of a wire screen when used to the window.

Instead of the spring applied to act upon the bolts, as shown, there may be a friction brake or spring to each bolt, in which case the bolt would have to be moved each way by the knob or by the key.

I claim as my invention- 1. -The sash fastener or lock, as made with the perforated bolt carrying projection B, to extend into and make part of the partingtongue of two sash-grooves, as set forth, and with the two bolts D E arranged with the said projection and in the lock-case A, in manner, and so as to operate substantially as set forth.

2. The two bolts D E, the abutments c f, the spring F, the bolt-case A, and the partingtongue portion or projection B, combined and arranged substantially as specified.
